One of the highest priorities of New Jersey employers is to promote safety in their workplaces. Drug and alcohol use, however, can contribute to workplace accidents and create a hazardous environment. One method employers use to combat these dangers is drug testing, either before employees are hired or during their employment (or both). Although New Jersey does not have any laws regulating or restricting drug testing in the workplace, case law provides some guidance on the circumstances in which employer drug testing is permissible.
